I just got my statement for my mr price account, my personal email address was not working so I couldn’t see my statement So today I received my statement and I noticed I have airtime purchases that I didn’t do, so I called your account department and they told me this has been going on since my account was opened in June, so please I want to know who is purchasing airtime with my account and I want all my money back and further close this account.
